Abstract

According to an aspect, there is provided an apparatus for a drive for driving an externally excited synchronous motor. The apparatus comprises means for performing the following. The apparatus causes the drive to operate in a primary operating mode for achieving unity power factor. The apparatus monitors stator flux linkage load angle, stator flux linkage and torque references. In response to the stator flux linkage load angle reference, in a steady state, reaching or exceeding a pre-defined maximum allowed stator flux linkage load angle for steady state operation, the apparatus causes the drive to operate in a stator flux assistance operating mode. In the stator flux assistance operating mode, an increased stator flux linkage for allowing operation with the pre-defined maximum allowed stator flux linkage load angle with unity or maximized sub-unity power factor is used as the stator flux linkage reference.
